            System.out.println(CONSTANTS.CONTENTS + content.getContentLocation());

        }/*from   w  ww . j  a va2  s  . c o m*/
        String finalZip = zipFile.zipIt(CONSTANTS.CONTENTS + fileName);
        //            System.out.println(finalZip);
        //            if(finalZip!=null){
        //                contentUpdateService.updateContentStatus(id,Boolean.FALSE);

        FileSystemResource file = new FileSystemResource(finalZip);

        //            return ResponseEntity.ok().contentLength(file.contentLength())
        //                    .contentType(MediaType.parseMediaType("application/octet-stream"))
        //                    .header("Content-Disposition", "attachment; filename=" + fileName)
        //                    .body(new InputStreamResource(file.getInputStream()));

        return ResponseEntity.ok().contentLength(file.contentLength())
                .contentType(MediaType.parseMediaType("application/zip"))
